243 A 236 A Learning optimization from nature Numerical optimization techniques such as genetic algorithms and simulated annealing can be used to quantify traditional trial-and-error learning methods. Ronald E. Shaffer of the Naval Research Laboratory and Gary W. Small of Ohio University describe how these techniques can be applied to analytical chemistry.
